model a rear spring i.d

I have this frame for my model a and I need to purchase everything to bolt a gm 10 bolt in place. What spring is this. I have my banjo rear-end mocked into place now and that makes the thing sit to high imo

 

need to i.d spring in the left attachment.

 

You have a Model A spring in the "spring over" configuration.

You want a 1935-1940 spring in the "spring behind" configuration.

You're going to have to cut and move your rear crossmember if you want to go "spring behind" if your rearend is currently located in the correct spot.

 

The spring in the first picture appears to be an aftermarket "Posies Super Slide" mounted in a "spring behind the axle" configuration. It is prolly a custom application based on a conversion with one of Posies experienced personel.
It's hard to tell from your pictures, but your frame is prolly set up for a spring behind the axle configuration also. You need to mock up the rear axle that you plan to use with the rear wheel centered in the rear wheelwell and your body located properly on the frame to better be able to determine what you might need to mount the rear axle to the frame.
You can check out my frame build in the albums on my profile page.
